Interesting you should mention the long "burn-in" period of the Belles amps. My SA-30 has some 350+ hours of use as is, and the latest 50 hours or so has really seen it blossoming, and still continuing to do so. I've experienced a rather odd sonic development, whereafter the first 50-75 (or even 100) hours or so the sound began tilting towards the slightly meager and pale, even somewhat hard at times, but during the last weeks it has settled into a wonderfully organic, free-flowing, resolving, and coherent presentation - indeed extremely impressive. Music just pours out of the speakers, unrestrained and alive.
My 150a ref v2 took roughly 850 hours to reach it's peak. As good as it was about every week I was happily suprised that new nuances of sound for a more positive and natural presentation would rear it beautiful head.I don't know if most wait long enough on these to rear them at their best. But from about 200 hours mine was about 90%-95% there. And at that point even the amp was a stellar performer.
